01/10/2018 – Ephemeris – One lone, but invisible, bright planet in the evening, the rest in the morning

January 10, 2018 Comments off

Ephemeris for Wednesday, January 10th. The Sun will rise at 8:18. It’ll be up for 9 hours and 3 minutes, setting at 5:22. The Moon, 2 days past last quarter, will rise at 3:20 tomorrow morning.

Let’s take our weekly look at the bright planets. While Uranus and Neptune are evening planets, they require binoculars or a telescope to spot. All of the bright naked eye planets save one are in the morning sky now, but Venus is too close to the Sun to be seen. So is Saturn, but that’s in the morning sky along with Mercury. At 7 this morning Jupiter is in the east-southeast and is a lot brighter than Mars, just below and left of it. Jupiter will rise at 3:29 tomorrow with Mars following at 3:40. If you want to take a crack at Mercury, it will rise this morning at 6:52 And Saturn will rise at 7:07 this morning. Saturn’s rise times will increase by 3 to 4 minutes each morning. The morning sky you’ll see at 7 a.m. will be the same stars as in the late spring sky with the summer triangle just rising.

The times given are for the Traverse City/Interlochen area of Michigan. They may be different for your location.
